To (LM whom t my concern:

Be it known that I, Bennr GaeLLUs, of Madison, in the county of Done,State of Wiscousin, heve invented certein new and useful Improvements inVaporizing Devices for Internal-Combustion Engines; and l do herebydeclare the following to be a full, clear, and exact description ofthesame, reference being had to the accompanying drawings, forming a. artof this specification, and to the letters o reference marked thereon.

This invention relates to devices for commingling hydrocarbon liquid andair to form an explosive mixture for use in internal-combustionengines/the objects of the invention being to provide an inexpensive,compact, and simple device in which the admission of hydrocarbon iscontrolled by the suction of the engine Without requiring theintroduction of obstructions in the feed-pipe and Wherewith the airmayfbe caused to poss directljiVT over and around the hydrocarbon-inletend at right angles thereto to effect a more perfeet atomizing eifect. Y

The invention consists in certain novel details of construction andcombinations and arrangements of parts, all as will be now described,and pointed out particularly vin the appended claims.

Referring to the accompanying drawin s, Fi re 1 is a vertical sectionteken longitu( ina ly of the mixer. Fig. 2 is a sectional elevation atright angles to Fig. 1. Fig. 3 is a to lan view.

like letters of reference in the several ligures indicate the same arts.

The bod portion o the device is in ther form of a ttmg, whichconstitutes a part of the intake connections of the engine and et oneend is formed for direct connection with the intake-port of the engineor for connection with the pipe leading to said port. The coupling partsor ends may be flanged, as et A, or otherwise formed, as in ordinaryvpipe connections. The said body is provided with a straightintake-passage B, leading through the seme from end to end and et anintermediate point the gasolene-eed orifice enters the passage from theunder side, said vasolene-feed orifice bein through a nozzlelikeenlargement formed y projections C on the inside and C on the outside olthe iitting. The end of the orifice constituffs e valve-seat for apointed or needle valve extending vertically across the intake-passageand into a chamber E, located above the passa e B. The chamber Ecommunicates with-t ie passage B forward of the gasoieneorilicc througha port e, enterin e up er part of the chamber E, and a ove a 'aphragm ordisk-piston F, connected With lthe i valve i). Passages G lead from theoutside into the chamber beneath the diaphragm or disk F, andconsequently the partial vacuum created by the. suction of the enginelifts the diaphragm and valve, thereby opening the gesolene-ori'iice.

A removable cover H is provided for the chamber, and the end of thevalve-stem prefersbiy takes a bearing in an opening in .the cover tomaintain the proper siinernent of the velve. To re ulate the movement ofthe valve, an adjusts le stop, preferably in the form of a screw l, islocated in the cover H in position for the valve-stem to contacttherewith, end the stop is provided with e. handle or index I', whichmay register with grados-V.

tions on the periphery of the cover or chamber to indicate the!adjustment, as Willv be.

readily understoodI To prevent iiooding the en'ine, the iittin isprovided with s dam or Weill K forward o the asolene-orice, and in someinstances a sma escape lfor excess gasolene may be provided, osindicated by dotted lines at L.

lt will be noted that the projection C,

which constitutes the couplin for the gasolene-pipe, is concentric witht e chamber E and forms e convenient means for chucking the fitting tofinish up the chamber. The

whole device is of such form that it maj,r be readily cast. The onl thanthe usual coup ing connections and drilled ports is in the chamber andits cover, the outside ofthe latter being preferably ma.- chined topresent a better appearance.

Owing to the f act that in the referred construction and as illustratedt e diaphragm for controlling the valve is located in s chamber entirelyoutside of the air-passage, the letter is not restricted, and at thesame time in operation the valve will be opened, admlttin an appreciablequantity of air not mixed wit 1 gasolene.

Should an obstruction occur in the asolene-n ozzle, it may be quicklyand easilg removed, inasmuch as the nozzleis in s ement With thevalve-stem opening, and the cover of the chamber and valve may be easilyand quickly removed to give access to the nozzle.

In the broader aspect of the invention I d0 machine-Work other- Kpt Wishto belimited to the location l' the '4 'aphragm in a, chamber outside ofthe air Passage, although such location is very desirable and racticallefficient. Having tlius descri ed my invention, what I claim as new, anddesire to secure by lietters Patent, is-
